To whom t may eminem:

Be it known 'that E, NILLLAMA LORENZ,

a citizen of United States, residing at Hartford, in the county of Hartford and State of FCom'iecticut. yhave invented new`and useful improvements in Apparatus for Separating Molten Glass intoMold Charges, of which the following iisfa2 specication. v

ThisA invention relates to' apparatus for separating moltenglassinto mold charges, its object being to provide suitable means for obtaining mold charges either of uniweiglits or sizes, in a desired 'order of succes sion' from a single feeding machme for regular and continuous delivery to afplurality of' molds or shaping machines' operating 'in proper timed relation to the feeder.

In the present invention the molten glass icws from a furnace or'other suitable'supply source into a Vcontainer having a submerged outlet, through which the glass is intermittently discharged in .pulsatory movements by an impelling device locatedin the glass above the outlet.- For this purpose the impelling device has a periodic movement transversely ofor acrossl the outlet to'feed the glass thereto, and also has periodic plunging movements or strokes of. equal or varying lengths in the desired order of suc' cession, whereby to force regulated quantities 'of the glass rapidly down through the outlet, beneath which each gather thus expelled is momentarily suspended, until a mold charge is severed from it." Meanwhile'the impelling device, by reversal of one or both of its movements abov'eldescribed, retracts or reverses the glass in the outlet. This reversal may begin at or before, or after the severing-operation, either to neclrjor otherwlse shape the gather before severance, or to retract the stu'b during or,v after severance toward or into the outlet, so as to reheat it and remelt the vchilled scar resulting from lcontact with the shears.

The severed charges may be distributed 'and delivered to the molds or shaping machines by any suitable delivering apparatus, such as that shown in U. S. Patent 1,264,- 328 or 1,373,202.-

In -the drawings:- Figure 1 is a plan of a machine embodying the invention;

'Fig. 2 is a side elevation, partly in section, on line 2-2 of Fig. 1

v into the outlet;

-Fig. 4 is a sectional eievation on line 4.-4 of Fig. 1; v- Figs. 5 to 8 are like sectional elevations on line 5-5 of Fig. 3, showing the impeller at varying distancesabovet the discharge outlet; Fig. 5 showing the impeller in position to move downwardly to force a gather through the outlet; Fig. 6 showing the impeller at the bottom of its stroke with the extruded gather depending from the .outlet ready for severing; Fig. 7 showing the impeller after it has moved upwardly a slight distance from its lowermost position; and Fig. .8 showing. the impeller nearing the top of its ystroke with the-stub retracted Fig. 9 shows a cam for controlling the plunging, or up and'down movements of the im ller, and

ig. 10 shows a cam for controllingthe oscillation of the impeller transversely of the outlet.

The container 21 for the molten glass 20- is provided with a cover 22, said container having in its bottom a submerged discharge outlet 23, from which the gathers or masses are momentarily suspended forV severance by the shears 58, which may be of the type shown in Patent No. 1,264,328, or any other suitable severing. device connected in any well known manner to sever the suspended gathers in timed relation to their -poses the said gate Amay be omitted. The

gate, together with the walls of the container, form a basinover the outlet,and in this' basin the impeller 25 is mounted for controlling the ow of glass toward the outlet and also its discharge therethrough. The impeller maybe in the form 'of a wheel or segment and may have anydesired contour. It is preferably mounted for back and forth rotative movement upon a pair of "with hubs 30 clamped by means of bolts 31,

Q x i '15514959 rockerl arms .27 and` having.' bearings -338,1,1d 34 in which the shaft 35 (Fig. 3) is i journaled, said shaft extending through the' impeller and through its hub-like portions' V36, which abut the bearings -33 and 34 as shown:l Openings 37 are provided in the Walls of the container to afford suicient 't clearance for the up and down movement of the 'hubs of the impeller.- The forward ends gof the rocker arms 27-and 28 are provided i* en a sleeve 29, journaled`in bearings i32`on' the container.

A shaft38, mounted in suitable-bearings- 19 on a frame 18, is providedl with a pulley vof a set screw 76, is a cam member 41 (Figs. 1 fand 9) having a cam .path .formed with `two rises-42 and 60, the cam'path beino' engaged bye roll 43 upon a rock arm,44 pivotv ed at 45 to a bracket on the frame 19, (Fig.

2)i For conveniencev in changmg cams, so

l. tliatthe machine may be used for a variety the --sectionsbe'ing` heldA together by bolts- 'of work, each camdisk may be diametrically divided along the line 1071 (Figs.2 and 9),

' 65 which may also serve to clamp the disk to the drive shaft 38, 'in which case the set I. screw 76 may be omitted.- The upperend ofthe 'rock arm 44 ispivoted at-474e a block 55 slidably mounted upon a link 46,

the link being pivoted at 48 to an extension 49 projecting upwardly from the arm 27. By the-mechanismjust described, the cam member 41 serves to move the impeller back and forth toward and from the outlet, the

' strokes of the impeller varying alternately in length by an amount equal to the diii'erence between tliecam rises 42 and 60, which in the present case is the distance between theupper and lower radial lines 61 and 6 2 on the arcl 64. The distance between the radial lines 61 and 63, taken on the arc 64, is equal to the .longer strokeof the impeller, and the distance between the radial lines 62 and 63 on the arc 64 equals the shorter stroke of the impeller. Thus by alternately varying the strokes of the impeller, the size or weight of the gathers extruded through the Voutlet will also be varied andthe weight of the charges severed at i. regular intervals at a given plane below the outlet will vary accordingly.

Rotation of the impeller upon its axis, in the direction indicatedk by the arrow in lFig. 5, is utilized to periodically draw the glass forwardly. toward the outlet and into the'basin, for subsequent discharge through the outlet by the .next downward movement of the impeller. Reverse rotation of the i impeller, as indicated by the azlrow'in Fig.' .6, together with its upward movement, may

be utilized to retard the flow orto retract l.tlie pendant glass, either before or after,

path of the cam member 721 or during4 the severing operation, depending upon whether it is desired to neck orotherwise shape the gather previousto severing, or merely to retract the remnant stub 59 toward or'into the outlet to reheat or remelt it, 'or to prevent the glass'from piling on the shears during the severing operation,

van example ofthe necking of the athers beingv shown. by dotted lines in. ig. 6. Mechanism for imparting the back and' forth or rotative movement to the impeller upon the arms -or'supp'orts 27 and 28, com-y prises a cam member 72 adjustableon the shaft 38 by means ofthe set screw 76.' The cam member has acam path engaged by a roll 74 on the forward end 75 of a lever 68 havinga hub .portion 69 journaled on the reduced end `70 of a'shaft 71 projecting through the sleeve 29 (Fig. 1), the lever being heldupon the shaft 70 by anut 98.

'The .lever 68is provided with a sector 66 meshingwith a pinion 67 on the impeller shaft 35, said shaft4 and theimpeller thereon bein oscillated by the rocking" of the lever. ecured to the pinion 67 is a driving disk 84, vengagement with a similar disli 83 vfixed on the ratchetwheel 80 which is I keyed at 81 to the `impeller shaft 35. A sprin 82, interposed between the 'pinion and t ead'ustab e nuts 85, serves to maintain the dis 84. in driving engagement with the disk 83, adjustment'of the nuts serving to properly tension. the spring` 82. The cam igs. 1 and 10) is preferably provided wit two-.risesf.73 and 77, corresponding approximately to the rises of the cam member 41, so as to give alternate long and short rotative movements to the impeller back and forth transversely of and across the outlet, the longer movement being preferably employed in feeding the glass toward-the outlet with the impeller moving in the .direction indicated, by the arrow in Fig. 5. Rotation of the impeller in the opposite direction as indicated in Figs. 6 to 8, may begin about the time it reaches its lowermost position and may continue during the greater part of its upward stroke, at Awhich time the stub is retracted toward or drawn into the outlet. Rotation of the impeller in the direction indicated by the arrow in F ig. 5, to feed the glass to the outlet, may begin at or about the time the impeller reaches its uppermost vposition. The timing of the reversal periods, as controlled by the cam member 72, may be varied with respect to the plunging periods, or the" up, and down movements ofthe impeller, byv

adjusting either of the cam members41 or .72 on the shaft 38. The number and extent of the rises .for the cam lpath of the member V72 may be increased or decreased' to agree with .those of the cam memberv 41, or

-otherwise varied to produce the desired results.

duce chargesV of i equal sizes .in-succession,- a cam may be provided, proportmned to give the desirednumber of charges for eachf revo- I lution of the shaft 38-.1' y

Regulation of jthe vextent of Ythe vdownward movement ofthe .impeller is provided fon-so as to permit variation-of the distancebetween the outlet andthe-bottom of the impeller when in its lowermost position. i

Such ieguation is effected by-.a feed screw 52, held against longitudinalmovement by the collars.v 53, ythe-:screw .being turnedV by rotation 'of the handle 5 4 to lengthen vor shortenthe link V46 (Figf2).
